The 38K Bra Is Confidence for Curvy Figures
The 38K Bra: Expert Fit, Full Support & Confidence for Curvy Figures
The 38K bra size represents a unique intersection of a wider band and significantly fuller cup, often underserved in the lingerie industry despite growing demand. Women who wear a 38K deserve bras that prioritize comfort, structure, and style without compromise.
In this expert guide, we explore what a 38K bra size entails, why proper support matters, and how to shop confidently in a market that still lacks inclusivity for extended cup sizes.
What Does 38K Mean in Bra Sizing?
A 38K bra generally indicates:
- A 38 inch under bust measurement (ribcage circumference)
- A K-cup size, which typically reflects a 13 inch difference between the band and bust (in UK sizing; roughly an O-cup in US sizing)
This size is part of the full bust/full figure category and is designed to support substantial breast volume that requires superior engineering in lingerie construction, especially when you understand how bra size 38 bands interact with different cup volumes.
Size Perspective:
A 38K bra is not simply a larger version of a D cup, it requires an entirely different design approach involving:
- Wide set underwires
- Reinforced cup panels
- Strategic weight distribution
The band of a 38K bra should fit snugly and only be able to be pulled out about 2 inches from the back. Wide, padded, and adjustable straps should be used in a 38K bra to prevent digging and reduce shoulder/neck pain. The number 38 represents a 38 inch snug ribcage measurement, while the letter K indicates a large difference between under bust and bust measurements, typically 11-13+ inches depending on brand. Sister sizes for a 38K bra include 36L (smaller band, larger cup) and 40J (larger band, smaller cup). Full cup or balconette styles are ideal for a 38K bra, ensuring complete encasement of breast tissue without gapping or spilling. For a 38K bra, it is essential to have a secure band that sits parallel to the ground, broad cushioned straps, and full coverage underwired cups to prevent spillage and shoulder pain. A UK 38K indicates a 13-inch difference between the under bust and full bust measurements. A 38K bra is most commonly found in UK sizing, as many US brands do not manufacture cups this deep.
Compared to lower cup sizes such as 38D or 38C, a 38K provides deeper cup projection suitable for a larger bust. The gore of a 38K bra should lie flat against the sternum; if it lifts off, a larger cup size is likely needed. To find your exact fit, many experts recommend using the ABraThatFits Calculator to determine if you need UK or US sizing based on measurements. The band of a bra provides 80% to 90% of the support, making its fit paramount. Frequent re-measurement of bra size is recommended every 6 to 12 months due to weight fluctuations or aging. The K cup size in the US is equivalent to the H cup size in UK brands. The 38K bra size can be searched using the Universal Cup Sizing (UCS) system by entering 38D8.

Common Challenges for 38K Wearers
1. Limited Retail Availability
Mainstream lingerie brands often top out at G or H cups, leaving K-cup wearers with few accessible options unless shopping with specialty retailers or well-stocked online bra stores.
2. Structural Fatigue
Standard bras not built for K-cup breasts tend to collapse under the weight, leading to poor posture, shoulder indentation, and cup spillage.
3. Miss sizing
Many women end up in the wrong bra size, opting for looser bands and smaller cups due to lack of stock, leading to discomfort and inadequate support.
